Hi,
Pool is running XenServer 7.2

I want to add 2 more NICs on both Master and Slave.

First question:
should i plug all 4 NICs on a switch or is enough to connect NIC 3 from Master with NIC 3 from Slave and NIC 4 from Master with NIC 4 from Slave and then create BOND ?

Second question:
how can i reconfigure HA-Lizard to use the BOND ?

Thank you

presuming that you are referring to the replication interface, yes, you can plug them into a switch, but that will introduce a single point of failure. if you want to have a switch in between for some reason, the only redundant way would be to stack two switches and create LACP bonds that span both switches, otherwise you are better off directly attaching the replication ports of the hosts to eachother
